[ILUG] Last block on disk bad?

I run a cron job weekly to scan my disks for badblocks. On my brand-new
IBM UDMA-100 75GXP 30GB disk, the very last block is showing up as
Partition table is:
[root at excalibur /root]# fdisk -l /dev/hda
Disk /dev/hda: 255 heads, 63 sectors, 3737 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 31 248976 83 Linux
/dev/hda2 32 62 249007+ 82 Linux swap
/dev/hda3 63 3737 29519437+ 83 Linux
Running badblocks on /dev/hda3 says that 29519436 is bad. Running it on
/dev/hda2 shows 249004, 249005 and 249006 are bad.
I'm thinking that this is due to the partitions not ending with an
multiple-of-4 blocks (hence the + after the block count above).
Is this hypothesis correct, or do I really have a failing disk
(and it's just pure chance that the bad blocks are exactly at the
ends of partitions)?
